Cooling fluid supply apparatus with safety mechanism and method for cooling heat load

A cooling fluid supply apparatus with a safety mechanism, the cooling fluid supply apparatus comprising:

• a temperature adjusting portion configured to cause a cooling fluid and a heat-dissipating fluid to exchange heat with each other and adjust a temperature of the cooling fluid;
• and a user-pipe connecting portion for connecting the temperature adjusting portion to a heat load and a heat-dissipating fluid supply apparatus with user pipes disposed therebetween,
• wherein the user-pipe connecting portion includes a cooling fluid outflow pipe allowing the cooling fluid to flow from the temperature adjusting portion toward the heat load therethrough, a cooling fluid inflow pipe allowing the cooling fluid to flow from the heat load toward the temperature adjusting portion therethrough, a heat-dissipating fluid inflow pipe allowing the heat-dissipating fluid to flow from the heat-dissipating fluid supply apparatus toward the temperature adjusting portion therethrough, and a heat-dissipating fluid outflow pipe allowing the heat-dissipating fluid to flow from the temperature adjusting portion toward the heat-dissipating fluid supply apparatus therethrough, the user-pipe connecting portion further includes a first bypass pipe connecting the cooling fluid outflow pipe and the heat-dissipating fluid inflow pipe and a second bypass pipe connecting the cooling fluid inflow pipe and the heat-dissipating fluid outflow pipe,
• the first bypass pipe is connected to a first overheating prevention valve for opening and closing the first bypass pipe and to a first check valve for blocking a stream of the fluid from the cooling fluid outflow pipe toward the heat-dissipating fluid inflow pipe, and
• the second bypass pipe is connected to a second overheating prevention valve for opening and closing the second bypass pipe and to a second check valve for blocking a stream of the fluid from the heat-dissipating fluid outflow pipe toward the cooling fluid inflow pipe.
